Sensitivity range optimization of surface acoustic wave humidity ultrasonic sensors incorporating a polyvinyl alcohol (PVA) layer

Saliou Ndao, Marc Duquennoy, Christian Courtois, Mohammadi Ouaftouh, Mohamed Rguiti, Nikolay Smagin

In this paper, Surface Acoustic Wave (SAW) delay line (DL) based humidity sensors are optimized. These sensors comprise two ultrasonic interdigital transducers (IDT) for generating and detecting SAW. The SAWs propagate along a piezoelectric substrate covered with a polyvinyl alcohol (PVA) layer…

MEMS high temperature gradient sensor for skin-friction measurements in highly turbulent flows, Capteur thermique MEMS pour la mesure du frottement dans les éouclements fortement turbulents

Cécile Ghouila-Houri, Abdelkrim Talbi, Romain Viard, Quentin Gallas, Eric Garnier, Pascal Molton, Jérôme Delva, Alain Merlen, Philippe Pernod

This paper presents and discusses the results obtained with a MEMS high temperature gradient sensor for time-averaged and fluctuating skin-friction measurements in highly turbulent flows. Designed as a robust wall-mounted suspended hot-wire structure, the micro-sensor showed a high temperature…

Addressing Organic Electrochemical Transistors for Neurosensing and Neuromorphic Sensing

Mahdi Ghazal, Thomas Dargent, Sébastien Pecqueur, F. Alibart

We report on the comparison of two different driving circuits for addressing micro-fabricated organic electrochemical transistors of different channel resistances and transconductance, aiming for neuromorphic sensing. While the Current-Voltage converter observed faster transients, the Wheatstone…

Time domain reflectometry for improved Surface Acoustic Wave magnetic field sensor sensitivity

Aurelien Mazzamurro, Abdelkrim Talbi, Yannick Dusch, Cécile Ghouila-Houri, Philippe Pernod, Olivier Bou Matar, Nicolas Tiercelin

This paper shows the use of time domain reflec-tometry (TDR) applied to Surface Acoustic Waves (SAW) based magnetic field sensors to improve sensitivity of these devices. The basic operating principle of such sensors is the use of a magnetostrictive material along the SAW path to induce a velocity…

Numerical study of the reflected elastic waves using Rayleigh diffraction integral

Nadir Maghlaoui, Hakim Djelouah, Assia Oudina, Mohamed Ourak, Farouk Benmeddour

In this work, the transient ultrasonic waves radiated by a linear phased array transducer in a liquid then reflected at a liquid solid interface is studied. A model based on the Rayleigh integral is used where the reflection at the plane interface is considered by using the reflection coefficients…
